Message-Id: <1352467202-27903-2-git-send-email-thierry.reding@avionic-design.de>

Subject: [PATCH 1/2] ARM: tegra: Add Tegra20 host1x support
This commit adds the host1x node along with its children to the Tegra20
DTSI. Furthermore the OF auxiliary data table is updated to have proper
names assigned to the platform devices instantiated from the device
tree. Moreover, the clocks required by host1x and the two display
controllers are initialized and the pll_d frequency table is completed
with a few entries to support common HDMI and LVDS display modes.
